FIELD OF INVENTION

The present disclosure is directed to novel derivatives of citronellol and polycitronellol, particularly ethoxylated and propoxylated derivatives of citronellol and polycitronellol, and methods of making them, compositions comprising them, and methods for using them, particularly as surfactants.

BACKGROUND

Surfactants are a multimillion-dollar annual industry. Surfactants are generally molecules which have at least one strongly polar or ionic functional group and at least one strongly nonpolar or hydrophobic functional group, generally positioned at opposite ends of a largely linear molecule. Thus, one end of a surfactant molecule is usually hydrophilic, while the other end is hydrophobic. The unique chemical property of surfactants is their ability to dissolve in both aqueous media and nonpolar (hydrophobic) media by virtue of this amphiphilic divided structure. They find use in a variety of products, often at the junction between aqueous and hydrophobic environments, especially when they are used in soaps and detergents. Functionally, surfactants are often used as wetting agents, detergents, soaps, emulsifiers, foaming agents, and dispersants. They are also commonly used in a variety of multicomponent compositions in order to stabilize the interactions between hydrophobic and hydrophilic ingredients.

There are a variety of different classes of commercially available surfactants, most of which are derived from petrochemical feedstocks. These include anionic surfactants such as sulfates, sulfonates, phosphates, and carboxylates; cationic surfactants, such as quaternary amines; zwitterionic surfactants, such as betaines, sultaines, and amine oxides; and non-ionic surfactants, such as alkoxylates, and polyhydroxy fatty acid esters.

The use of alkoxylates, i.e., poly(ethylene glycol) or poly(propylene glycol) moieties, is common in several classes of surfactants. These include alkyl phenol ethoxylates and propoxylates, such as nonylphenol ethoxylates, aliphatic alcohol ethoxylates such as fatty alcohol ethoxylates and propoxylates, such as cetyl propoxylate, fatty acid ethoxylates and propoxylates, fatty amine ethoxylates and propoxylates, monoalkanolamide ethoxylates, sorbitan ester ethoxylates, ethoxylated glucosides, and glycerol esters (such as glycerol propoxylate), as well as polyether polymers such as poly(ethylene oxide), poly(propylene oxide) and ethylene oxide/propylene oxide copolymers.

Many alkoxylated surfactants are coming under increased scrutiny because of their toxicity, or for their lack of biodegradability resulting in environmental persistence. For example, nonylphenol ethoxylates, which were once very common in detergents, textile manufacturing and drilling mud, have been banned in Europe since 2005 due to concerns over environmental toxicity and persistence. Yet, in 2013, nonylphenol ethoxylates still accounted for almost half of global nonionic surfactant production, despite increasing calls for prohibition at the international level.

Thus, there is an urgent need for new alkoxylated surfactants, especially surfactants with improved stability, improved biodegradability, and/or improved environmental impact. It would be especially advantageous to have new surfactants sourced from renewable resources.

Terpene alcohols such as citronellol are renewable resources. Citronellol may be sourced naturally from such plant species as citronella grass, or prepared semi-synthetically by hydrogenation of geraniol or nerol, themselves natural resources derived from, respectively, geranium grass, and lemongrass. Geraniol and nerol and other related terpenes can also be derived from the pyrolysis products of beta-pinene, which is widely available from numerous botanical families (e.g., cumin, hemp, hops, cannabis, cluster pine, and Clausena anisata).

Terpene alcohol derivatives include polymers and oligomers of terpene alcohols. For example, citronellol has been formed into useful oligomeric and polymeric products having the following structure:

wherein n is an integer from 0 to 20 (e.g., 0-3). Dimers, trimers, and other oligomers of citronellol have been described. See, e.g., US2017/0283553, US2020/0165383, and US2020/0392287, the contents of each of which are hereby incorporated by reference in their entireties. One of the benefits of this class of polymers is the reversibility of the polymerization chemistry which creates them from citronellol. As a result, these polyether polymers are biodegradable, reverting to citronellol naturally. Alkoxylated polymers based on polycitronellol would thus also be expected to be biodegradable, providing a much more environmentally friendly and renewable-resource based BRIEF SUMMARY OF THE INVENTION

In a first aspect, the present disclosure provides citronellol and polycitronellol alkoxylate surfactants, derived from citronellol monomer or polycitronellol oligomers and derivatives thereof. These compounds are useful in numerous types of compositions, and numerous roles. For example, these compounds may be used as wetting agents, detergents, soaps, emulsifiers, foaming agents, dispersants, buffers, preservatives, and are especially useful as ingredients in personal care compositions, cosmetic compositions, food compositions, and crop care compositions.

In a second aspect, the present disclosure provides a method of preparing such compounds.

In a third aspect, the present disclosure provides compositions and products comprising such compounds. In some embodiments, said compounds are useful in a variety of applications, including as or in cosmetics, soaps, hair care products, fragrances, sunscreens, household cleaning products (e.g., laundry detergents), plastic additives, paints, coatings, lubricants, surfactants, insecticides, and herbicides.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the term “polycitronellol” refers to a polymer having the following structure, saturated or unsaturated:

wherein n is an integer from 0 to 20 (e.g., 0-3). While other polymeric derivatives of citronellol may be possible (i.e., having a different structure or nature of connectivity), these are not embraced by the term “polycitronellol” as used herein. The polycitronellol polymers described herein are derived from polymerization of the alcohol groups of citronellol with the alkene groups by an alkene addition reaction. These polymers can undergo a depolymerization based on an elimination mechanism, providing alcohol and alkene products.

The term “alkyl” as used herein refers to a monovalent or bivalent, branched or unbranched saturated hydrocarbon group having from 1 to 20 carbon atoms, typically although, not necessarily, containing 1 to about 12 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, t-butyl, octyl, and the like. The term alkyl also may include cycloalkyl groups. Thus, for example, the term C6 alkyl would embrace cyclohexyl groups, the term C5 would embrace cyclopentyl groups, the term C4 would embrace cyclobutyl groups, and the term C3 would embrace cyclopropyl groups. In addition, as the alkyl group may be branched or unbranched, any alkyl group of n carbon atoms would embrace a cycloalkyl group of less than n carbons substituted by additional alkyl substituents. Thus, for example, the term C6 alkyl would also embrace methylcyclopentyl groups, or dimethylcyclobutyl or ethylcyclobutyl groups, or trimethylcyclopropyl, ethylmethylcyclopropyl or propylcyclopropyl groups.

The term “alkenyl” as used herein refers to a monovalent or bivalent, branched or unbranched, unsaturated hydrocarbon group typically although not necessarily containing 2 to about 12 carbon atoms and 1-10 carbon-carbon double bonds, such as ethylene, n-propylene, isopropylene, n-butylene, isobutylene, t-butylene, octylene, and the like. In like manner as for the term “alkyl”, the term “alkenyl” also embraces cycloalkenyl groups, both branched an unbranched with the double bond optionally intracyclic or exocyclic.

The term “aryl” as used herein refers to an aromatic hydrocarbon moiety comprising at least one aromatic ring of 5-6 carbon atoms, including, for example, an aromatic hydrocarbon having two fused rings and 10 carbon atoms (i.e., a naphthalene).

By “substituted” as in “substituted alkyl,” “substituted alkenyl,” “substituted alkynyl,” and the like, it is meant that in the alkyl, alkenyl, alkynyl, or other moiety, at least one hydrogen atom bound to a carbon atom is replaced with one or more non-hydrogen substituents, e.g., by a functional group.

The terms “branched” and “linear” (or “unbranched”) when used in reference to, for example, an alkyl moiety of C_(a) to C_(b) carbon atoms, applies to those carbon atoms defining the alkyl moiety. For example, for a C₄ alkyl moiety, a branched embodiment thereof would include an isobutyl, whereas an unbranched embodiment thereof would be an n-butyl.
